Purpose

To evaluate the clinical feasibility and outcomes of using the Yamane technique for intraocular lens (IOL) fixation in pediatric patients with ectopia lentis and inadequate capsular support.

Setting

A retrospective interventional case series conducted at a tertiary referral academic ophthalmology center.

Methods

We present a surgical video and three pediatric patients with bilateral ectopia lentis, associated with Marfan syndrome and severe zonular dialysis involving more than 6 clock hours. Due to the absence of appropriate capsular tension rings or insufficient residual capsule, a crystalline lens removal combined with sutureless flanged intrascleral IOL fixation using the Yamane double-needle technique was performed. The surgical technique emphasized careful centration, early externalization and flanging of the leading haptic.

Results

All three patients showed significant visual improvement postoperatively with stable IOL positioning. No major intraoperative complications were noted. One patient required YAG laser capsulotomy for capsular opacification. The Yamane technique demonstrated minimal conjunctival trauma, and reduced risk of long-term complications such as suture breakage or optic capture. Astigmatism remained within acceptable limits and No IOL decentration or tilt was observed during follow-up. The video demonstrates key steps for successful adaptation of the technique in pediatric eyes.

Conclusions

The Yamane technique appears to be a safe and effective surgical option for pediatric ectopia lentis with extensive zonular weakness, offering stable IOL fixation without the need for sutures or glue. Further prospective studies are needed to validate long-term safety and efficacy in the pediatric population.
